RUDOLF A. BAUMGARTNER, OF ROSENHEIM, BAVARIA, GERMANY.

MACHINE FOR CLEANING BARLEY.

SFECIFIGATION forming part of Letters Patent No. 433,160, dated July 29, 1890.

Application filed February 6, 1890. Serial No. 339,421. (No model.) Patented in Germany May 16, 1889, No. 46,902, and in England May 21, 1889,110. 8,426.

To all whom it may concern.-

Be it known that I, RUDOLF A. BAUM- GARTNER, of Rosenheim, Zavaria, Germany, have invented an Improved Machine for Cleaning Barley, (for which I have obtained a patent in Germany, No. 46,902, dated May 16, 1889, and in England, No. 8,426, dated May21, 1889,) of which the following isa specification.

This invention relates to a machine which will clean and wash barley, so as to remove the dust, sand, and other dirt without destroying the germinating properties of the barley.

It consists in the various features of improvement more fully pointed out in the claims.

I11 the accompanying drawings, Figure l is a sectional elevation of my improved machine for cleaning barley. Fig. 2 is a horizontal section on line m 00, Fig. 1; and Fig. 3 a horizontal section on line y y, Fig. 1.

The letter A represents a water-tank, in which my improved machine is placed. This machine consists of a bed-plate d, from which project upwardlyaseries of columns (1 The space inclosed by these columns is divided into three stories B C D by the horizontal partitions d. Centrally through the machine there extends a hollow shaft E, receiving rotary motion by bevel-gear from the workshaft A. To the shaft E are connected by radial arms 11 a pair of brushes 1), that are revolved by the shaft in a horizontal plane. The workingsurface of these brushes is placed directly above the uppermost partition (I, as shown. This partition is provided with an opening 6, that communicates with an annular working-chamber formed within the two lower compartments B C. The second partition d has an opening 6 diametrically opposit-e opening 6, and the lowermost partition has an opening E in line with such opening 6. The annular working-chamber in compartments B C is formed by two annularbrushes facing each otl1erviz., an outer fixed brush 0 and an inner rotating brush 6. The outer brush 0 is secured to a perforated cylinder 0 which permits free exit of the dirty water. Clean water is fed to the outer brush by water-pipe a The inner brush 0 is secured to a drum 0 held in place by a set of radial tubes to, proj ecting radially from hollow shaft E and communicating with a water-tube a within such shaft. The tubes aa' cause constant streams of clean water to enter the working-space between the brushes 0 c'.

In use the machine is set in motion to re volve brushes 1) and the brush 0. The barley to be cleaned is admitted through hopper b and is by brushes 1) subjected to a preliminary cleaning and swept through openings e into the annular working-space. \Vithin this space the barley is subjected to the action of the brushes 0 c and to the water. As the barley descends through the openings in the two lowermost partitions d, it is properly cleaned, until it finally reaches the discharge-opening E. From this opening, the cleaned barley is removed by a suitable conveyerm.

\Vhat I claim is 1. The combination of a water-tank with a revolving shaft, a cylindrical brush secured thereto, an outer brush forming a workingchamber with the inner brush and pipes for conducting water to such working-chamber, substantially as specified.

2. The combination of a water-tank with a revolving shaft, horizontal brushes b secured thereto, a revolving brush 0, also secured thereto, an outer brush 0' opposite brush 0, and pipes for conducting water between brushes 0 c, substantially as specified.

3. The combination of an open vessel with a set of partitions, a working-chamber com- .posed of a fixed and a movable brush, a perforated backing for the fixed brush, a revolving shaft, to which the movable brush is secured, brushes 1), revolving above the working-chamber, and pipes for admitting water to such chamber, substantially as specified.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
